As seen in Kingdome Come, Captain Marvel clearly has the advantage because Superman is vulnerable to "magic" which has been said that C.M.'s power comes from. However, I have always wondered why C.M. cannot control the lightning. He has the power of Zeus, yet he can't wield it. I think it would be interesting if he could control it the same as Superman's heat vision. Not only to transform him, but to use as a weapon.
